Flotation Reagent an overview | ScienceDirect Topics

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

pH MODIFIERS The selectivity in complex flotation processes is dependent on a delicate balance between the reagent concentration and the pH. This pH factor is modified with the help of the substances called pH MODIFIERS.

1. Introduction. A typical reagent regime for scheelite flotation is called the “lime flotation process”, which involves the addition of lime and sodium carbonate as copH modifiers, sodium silicate as a depressant and oleic acid (or sodium oleate) as the main collector (Vazquez et al., 1976, Yongxin and Changgen, 1983, Martins and Amarante, 2012).

Flotation Reagents Mineral Processing Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

The main challenge in scheelite flotation lies in the contamination of the concentrate by other calciumbearing minerals, mainly calcite. To remedy this problem, sodium silicate is frequently used as a depressant. According to the literature, one hypothesis for the mechanism of water glass consists in its absorption onto calcite through colloidal silica formation, preventing hydrophobization ...
